Detailed Description

Creates basic geometry for prototyping levels.

It automatically creates physics collision geometry and also sets up rendering occluders to improve performance.

Member Function Documentation

◆ DeserializeComponent()

void plGreyBoxComponent::DeserializeComponent ( plWorldReader & inout_stream)
overridevirtual

Override this to load the current state of the component from the given stream.

The active state will be automatically serialized. The 'initialized' state is not serialized, all components will be initialized after creation, even if they were already in an initialized state when they were serialized.

Reimplemented from plComponent.

◆ GetLocalBounds()

plResult plGreyBoxComponent::GetLocalBounds ( plBoundingBoxSphere & ref_bounds,
bool & ref_bAlwaysVisible,
plMsgUpdateLocalBounds & ref_msg )
overrideprotectedvirtual

Called by plRenderComponent::OnUpdateLocalBounds(). If PL_SUCCESS is returned, bounds and bAlwaysVisible will be integrated into the plMsgUpdateLocalBounds result, otherwise the out values are simply ignored.

Implements plRenderComponent.

◆ OnActivated()

void plGreyBoxComponent::OnActivated ( )
overrideprotectedvirtual

This method is called when the component gets activated.

By default a component is active, but it can be created in an inactive state. In such a case OnActivated() is only called once a component is activated. If a component gets switched between active and inactive at runtime, OnActivated() and OnDeactivated() are called accordingly. In contrast Initialize() and Deinitialize() are only ever called once.

See also
OnActivated(), OnDeactivated(), Initialize(), Deinitialize(), OnSimulationStarted()

Reimplemented from plRenderComponent.

◆ SerializeComponent()

void plGreyBoxComponent::SerializeComponent ( plWorldWriter & inout_stream) const
overridevirtual

Override this to save the current state of the component to the given stream.

Reimplemented from plComponent.

◆ SetIncludeInNavmesh()

void plGreyBoxComponent::SetIncludeInNavmesh ( bool b)

Whether the mesh should be an obstacle in the navmesh.

Note
This may or may not work, depending on how the navmesh generation works. Dynamic navmesh generation at runtime usually uses the physics colliders and thus this flag would have no effect there.
